Specification of Letters Patent.

To all whom t may concern:

Be it known that l, JULIUs H. SCHLAFLY,

, My invention relates to improvements in sheet metal structures andmore particularly to a chute for a silo, being especially adapted for asheet metal silo such as shown and described in my application forUnited j States patent on silos, Serial No. 768,239,

iled May 17, 1913.

The objects of the invention are, to generally improve constructions ofthe character indicated, to provide an inclosure suHiciently large topermit a man to climb a ladder inside thereof, said inclosure beingconnected to the silo and extending upwardly over the vertical series ofdoors therein, so that access to anyone of said doors may be gained byclimbing through said inclosure, said inclosure also acting as a chuteto direct ensilage thrownV out 'of any of said doors downwardly andprevent the same being blown about or becoming scattered.

Further objects yare the construction of said chute from sections, whichmay be shipped in knocked-down condition and conveniently erected inconnection with the erection of the silo itself `or after said silo hasbeen completed, as may be desired, the mode of connection ofthe varioussections con` stituting the chute, also the connection of said sectionsto the silo proper being important features.

rThe objects thus indicated, together with other objects which will bereadily apparent to those skilled in the art, may be attained by theconstruction illustrated inthe accompanying drawings, although theinvention may be embodied in other forms, the construction illustratedbeing chosen by way of example.

In thedrawings Figure 1 is a fragmentary perspective view,.illustratinga portion of a sheet metal silo and a portion of the silo chuteconnected therto, and embodying my--invention. Fig. 2 is a sideelevation of a completed silo, including the chute. Fig. 3 is afragmentary `perspective view illustrating a part of the silo sections,also a silo door frame, and the chute attaching bars connected tosaidsections and portions of Patented May 23, 1916..

the flanges broken away. Fig. 4 is a perspective view of two of thesections of the chute,` portions of the joint supporting strips, beingbroken away. Fig. 5 is a perspective View of one of the chute braces.Fig. 6 is a perspective view of one of the chute attaching bars. Fig. 7is a horizontal section view on the line 7-7 of Fig. 1. Fig. 8 is afragmentary perspective View illustrating portions of the silo sections,a portion of the chute section, and its connection to the silo section,parts being broken away. Fig.

9 is a vertical sectional view on the line p 9 9 of Fig. 4.

Throughout the several views similar reference numerals indicate similarparts.

More specifically describing the construction disclosed in saiddrawings, the numeral 1y indicates the roof and the numerals 2 the sheetmetal sections formin the sidey wall of the silo. rlhe said sections 2are provided with the horizontal, outstanding, plain ianges 3 at theirupper edges and the horizontal, outstanding ianges 4 at their loweredges, the depending flanges 5 being formed integrallywith said Hanges4.' ln the construction of the silo the sections 2 are arranged one uponanother and the flanges 3 and 4 connected, as by means of bolts 6, asclearly described in my said application Serial No. 768,239. rllhesections 2 are thus arrangedin a vertical series of tiers or courses,and preferably in alternate' tiers are larranged appropriate doors, oneof the frames, 7, of which is shown in Fig. 3. No claim, however, isherein made for the construction of said doors or frames. rlhe alternatesections between the doors are preferably provided with ladder rungs 8and the doors are provided with similar ladder rungs, as disclosed in mysaid specification, Serial No.`768,239`, thus producing a continuousladder extending up the side of the silo.

1t is of importance that in connecting the chute to the silo the wallsof saidl silo shall not be interrupted by apertures or fastening meansof any kind and for the purpose of forming 'a frame or anchor to whichsaid chute mayl be connected, the chute attaching bars 9 are provided.These bars are preferably formed of sheet metal fand constitute anangled body portion having one iange l0 4adapted to extend outwardlyfrom the body'of the silo, and the i Section5 2. At both ends of eachbar the vflange 10 is bent overv at right-angles to 4flanges 25, alsopreferably provided with apertures 26. The flanges are adapted to formthe attaching flanges 12, and said attaching flanges are provided withbolt apertures 13 preferably somewhat transversely elongated forconvenience of adjustment of jthe parts in erecting the sections. Thebars 9 are of such a length that the flanges 12 en'- gage theunder-sides of the'flanges 3 and the upper sides of the flanges 4 of thevarious wall sections and bolts 14 extending through thefianges 3, 12and 4 serve to connect the bars to the silo wall. In arrangingthe bars9, they are preferably disposed end to end in vertical series at the twosides of the doors,

so that one bolt 12 will extend through the.

lower flange of the bar 9, the flange 4 of the section'on which the baris arranged, the flange 3 of the subjacent section and the upper flange12 of; the subjacent bar 9, as

clearly illustratedin Fig. 3. The outstandsufficient distance thereaboveto give easy ing flanges 10 of the bars 9 are provided with boltapertures 15 for the chute section attaching bolts, `as hereinafterdescribed.

The chute preferably does not extend enaccess to the interior and topermit arranging an ordinary wagon beneath the lower end to receive theensilage in cases where it desired to haul the same away from the s o. jA vEach chute section is preferably formed of .sheet metal, having abody portion 16, which extends outwardly from the silo wall at one sideof the doors, is Aprovided with a curved, outer portion and returnstothe silo wall in a substantially straight portion at the oppo;

4 site side. At the two ends of each section are provided the inturnedflanges 17 and in the Walls of the body portion 16 are provided aplurality ofbolt apertures 18 corresponding to the apertures 15 in thechute attaching bars 9. The flanges 17 adapted to bearranged between theflanges 11` of thebars 9 and the silo sections 2 with the bars 9 ar-'ranged within the "interior of the angle produced by the flange 17.Bolts 19 are em- `ployed, extendingthrough the apertures 15` and 18l tosecure the -chute sections to the` ably of light 'channel ironconforming to the contour of the' chute'sectionsfbolts 21, with theirnuts'arranged withn'thechannel of the strip 20, belng provided for'connecting the chute sections'together and to said strip.

For the purposeof preventin any lateral movement of the chute with reation to the silo, and to strengthen' and support the structure, thechute-braces 22 are provided,

6 used in fastening the silo sections together extend through theapertures 24 completing the' fastening lof the brace.

v ne of said braces is preferably employed at each joint between chutesections and at each side of.

the chute. r

- The uppermost chute section differs from per edge is not parallel toits lower edge,

portion of the body 16. For the purpose of inclosing the top of thechute the sheet metal roof section 27 is provided, the inner end ofwhich engages the outer side of the sections 2 and the other edges ofwhich are formed with a flangeat28 bent down over `the outer side oflthe uppermost section,

bolts 29 extending through said flange and the body of the uppermostchute section to hold the roof in place.

In that part ofthe roof section 27 adjacent the silo lis arranged a trapdoor 30,

` preferably provided with hinges at `31 so as ,but is declined Afromthe ends where the flanges 17 are arranged to the ou'ter curved to openoutwardly and downwardly, away from' the .main roof 7of the silo. Thistrap door is suiiciently lar e to permit a man to pass therethrough inorder to emerge from the top of the chute inorder toireach the manholes-in the roof 1, one of the same being illustrated at 32. l

In addition to the trapl door 30 thereof section 27 is also providedwithv a small skylight 33, which will permit suliicient light `to enterthe chute to make the, doors and ladder rungs visible. .Whilethedrawings and above specification disclose the best'mode in whichv Ivhave contemplated embodying my' invention, I 'l desire to be not limitedto the ldetails of such disclosure, formany changes in form vandconstruction may be made, as circum-A stances require or experiencesuggests, with; out departing from thesprit of the inven tion', withinthe scope of the appended e claims.
